| 中文摘要: |
| 考察了室温下PP/EPDM/玻璃微珠三元复合材料的冲击过程。在不同玻璃微珠含量和填料表面处理等条件下，研究了裂纹扩展力、冲击断裂时间、冲击断裂功等参量的变化规律和相互关系。研究结果表明，随着玻璃微珠体积分数的增大，试样的惯性功呈线性形式增大；采用马来酸酐接枝EPDM，有利于改善其应力分布，提高材料的冲击韧性。 |
| 英文摘要: |
| The Izod impact process of PP/EPDM/glass bead ternary composite at room temperature was studied.The relationship of crack extending force，impact rupture time and impact break power with each other for the composites with different glass bead contents and different filler surface treatments was investigated.The results showed that the inertial power of the sample increased linearly with the increase of the glass bead proportion by volume；the use of maleic anhydride-graft EPDM was beneficial to the improvement of stress distribution and impact resistance of composite. |
